Nozomi(のぞみ, "Wish") is the fastest train service running on the Tokaido/Sanyo Shinkansen lines in Japan. The service stops at only the largest stations, and along the stretch between Shin-Osaka and Hakata, Nozomi services using N700 series equipment reach speeds of 300 km/h (186 mph). The trip between Tokyo and Osaka, a distance of 515 kilometres, takes 2 hours 22 minutes on the fastest Nozomi.[1]

The Nozomi name was first used for long-distance express services operated between Busan in Japanese-occupied Korea and Mukden (now Shenyang) in the former Manchukuo (now China) from 1934.[5] From 1938, the services were extended to run between Busan and Hsinking (now Changchun) in Manchukuo. The 1,530 km journey from Busan to Hsinking took over 29 hours, with an average speed of 52 km/h (32 mph). The services were run down between 1943 and 1944.[5]

Nozomi shinkansen services commenced on March 14, 1992 using new 300 series trainsets with a top speed of 270 km/h. From March 1997, 500 series trainsets were introduced on Tokyo - Hakata Nozomi services, running at a maximum speed of 300 km/h and covering the section between Shin-Osaka and Hakata in 2 hours 17 minutes.

700 series trains were introduced on Nozomi services in 1999, and N700 series trains were introduced from July 1, 2007, initially with four daily round-trip runs. All through Nozomi services (Tokyo–Hakata) were operated by N700 series trains by 2009, and all regularly scheduled Nozomi services were operated by N700 trains by 2011.
